Participant Media has come aboard to produce and finance Green Book, the Amblin Partners film that is set to star Viggo Mortensen and Mahershala Ali. Peter Farrelly is directing, and Linda Cardellini has just joined the cast. The pic is set to start principal photography this week.

Penned by Farrelly, Nick Vallelonga and Brian Currie, Green Book tells the true story of Tony Lip, an Italian-American bouncer with a seventh-grade education who in 1962 was hired to drive Dr. Don Shirley, one of the world’s finest jazz pianists, on a concert tour from New York City through the pre-civil rights-era Deep South. The men relied on the Negro Motorist Green Book to guide them to the few motels, restaurants and gas stations they could use below the Mason-Dixon Line.

Participant’s Jim Burke, Charles Wessler and Farrelly are producing with Vallelonga and Currie. Executive producers are Participant’s Jeff Skoll and Jonathan King, along with Cinetic Media’s John Sloss and Steve Farneth as well as Kwame Parker.

The film will be released via Participant’s output arrangements with Amblin Partners.

Mortensen is represented by UTA, Rawlins Company and attorney Stuart Rosenthal. Ali is with WME, Anonymous Content and Sloane Offer. Cardellini is repped by ICM Partners and Mosaic.
